If you look closely at picture 5 & 6 (logo closeups) there seems to be a gap there that could indicate a two piece battery tube. We'll need Manafont to confirm this in addition to providing a picture of the LED assembly.
If it splits over there which is much closer to the head than the other variants like SR3800 or TF-3T6, then it is highly probable that we can use 2 x 18350 IMRs (the bestinone ones which are tested to be really good by a few guys). The other variants are usable with 2 x IMR 18500. Extremely powerful pocket rocket, together with the DRY 3 x XM-L in DD 3-mode driver. Sizes would be around the same but this would be way lighter.
If for one reason or another you feel that you have too many triple XM-Ls and can sacrifice your SBOMZ coz you have this Sky Ray and the Dry, you can just take out the driver and solder the 2 wires directly to the backing of the driver. Run 3 cells direct drive. If you have a hobby driver you can charge to 4.1V, under load the sag is great. Still over 4 amps so on the lux meter it starts off at 310 lux reflected ceiling test and within 5 seconds it drops to 250 lux. Still 250 lux is in the same ballpark of my TK70 (probably get around 220-230 lux). If it gets real cold in Belgium like in the mountains or something, i am very sure you can maintain that 300s level, because i get it to somewhat maintain that for 1 minute when the head portion is cooled with ice. That would be approx 2800-2900L OTF.
Will do. My SkyRay 3800 Rev. 2 was only pulling around 2.4 amps at the tailcap with fully-charged TrustFires. Hopefully this one will push closer to 3 amps.
No, it'd explode if they do make a driver capable of doing that. It'd pull like 5 amps or more for a Li Co. Even for a Panasonic 3100 it'd get really hot and probably very dangerous due to the heat from both the battery + even more dumped from the LEDs and driver.
But it'd run on short bursts on 2 x 18350 IMRs though, if the tube can split, this one seems to split pretty close to the head.
I'd really like to see a comparison review of the Trustfire TR-3T6 vs. this Skyray 818. Any opinions on the best 3*XML flashlight? Why would you buy one over the other? I would lean toward the Skyray 818 just because of it's much better styling.
